Personalized learning through projects is one answer
One thing that this pandemic has done is to create an opportunity for more relationship building between student and teacher which is the basis, I believe, for SEL in school, good academic instruction, and so much more. That said, the next step - which I feel needs to be emphasized far more - is to personalize education through project-based or problem-based learning. When students have some control over what they focus on, choices in learning, a chance to use their own voice, ability to work at their own pace, perhaps empowered to solve a community problem - then a lot of social-emotional needs are met through the actual work. See Kevin Brookhouser's book, "20time Project" for how it's done.
